We use the National Health and Nutritional Examination Survey (NHANES) III to examine the effect of the availability of the school breakfast program (SBP). Our work builds on previous research in four ways: First, we develop a transparent difference-in-differences strategy to account for...

Birth weight has emerged as the leading indicator of infant health and welfare and the central focus of infant health policy. This is because low birth weight (LBW) infants experience severe health and developmental difficulties that can impose enormous costs on society. But would the prevention...

Prekindergarten programs are expanding rapidly, but to date, evidence on their effects is quite limited. Using rich data from Early Childhood Longitudinal Study, we estimate the effects of prekindergarten on children's school readiness. We find that prekindergarten increases reading and...

One in five U.S. youngsters has a mental disorder, but we know little about the effects of these disorders on outcomes. We examine U.S. and Canadian children with symptoms of Attention Deficit Hyperactivity Disorder (ADHD), the most common child mental health problem. Our innovations include the...

We examine the impact of air pollution on infant death in California over the 1990s. Our work offers several innovations: First, many previous studies examine populations subject to far greater levels of pollution. In contrast, the experience of California in the 1990s is clearly relevant to...

This study examines trends in labor force involvement, household structure, and some activities that may complicate the efforts of parents with young children to balance work and family life. Next I consider whether employer policies mitigate or exacerbate these difficulties and, since the...

This paper documents a counter-cyclical pattern in the health of children, and examines whether this pattern is due to selection of mothers choosing to give birth or due to behavioral changes. We study the relationship between the unemployment rate at the time of a baby's conception and parental...

Young children in poor communities are spending more hours in non-parental care due to policy reforms and expansion of early childhood programs. Studies show positive effects of high-quality center-based care on children's cognitive growth. Yet we know little about the effects of center care...

We argue that the environment determines life span, using historical data to show that such indicators of environmental insults in early childhood and young adulthood as quarter of birth, residence, occupation, wealth, and the incidence of specific infectious diseases affected older age...

We estimate the effect of poor child health on the labor supply of mothers and fathers post welfare reform, using a national sample of mostly unwed parents and their children-a group at high risk of living in poverty. We account for the potential endogeneity of child health and find that having...
